Abstract

The present invention relates to low-cost improvement of performance of multiple radio wireless access points. It relates to combinations of an antenna and one or more of a filter or an active components such as a power amplifier, low noise amplifier, switching diode or RF phase shifter (with a plurality of antennas), connected to the antenna connector of a radio component. Particular aspects of the present invention are described in the claims, specification and drawings.
